Proteomics of Halophilic archaea
Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2005Halophilic archaea is a member of the Halobacteriacea family, the only family in the Halobacteriales order. Most Halophilic archaea require 1.5M NaCl both to grow and retain the structural integrity of the cells. The proteins of these organisms have thus been adapted to be active and stable in the hypersaline condition.

The information transfer system of halophilic archaea
Plasmid, 2011Information transfer is fundamental to all life forms. In the third domain of life, the archaea, many of the genes functioning in these processes are similar to their eukaryotic counterparts, including DNA replication and repair, basal transcription, and translation genes, while many transcriptional regulators and the overall genome structure are more ...

Gas vesicle formation in halophilic Archaea
Archives of Microbiology, 1997Gas vesicles are intracellular, microbial flotation devices that consist of mainly one protein, GvpA. The formation of halobacterial gas vesicles occurs along a complex pathway involving 14 different gvp genes that are clustered in a genomic region termed the "vac region".

Diversity of lactate metabolism in halophilic archaea
Canadian Journal of Microbiology, 1995D-Lactate is readily used as a substrate for the growth of species of halophilic archaea belonging to the genera Haloferax and Haloarcula. L-Lactate was used by Haloferax species (Haloferax volcanii, Haloferax mediterranei) only when a substantial concentration of the D-isomer was also present in the medium.

Construction of composite transposons for halophilic Archaea
Canadian Journal of Microbiology, 1994Transposons with selectable marker genes (e.g., antibiotic resistance) have been extremely useful tools in bacterial genetics but have not been found naturally in Archaea. We constructed synthetic transposons consisting of halobacterial ISH elements (ISH2, ISH26, or ISH28) flanking a mevinolin resistance determinant.

Uranium association with halophilic and non-halophilic bacteria and archaea
Radiochimica Acta, 2004Summary We determined the association of uranium with bacteria isolated from the Waste Isolation Pilot Plant (WIPP), Carlsbad, New Mexico, and compared this with known strains of halophilic and non-halophilic bacteria and archaea.

Flagella of halophilic archaea: Differences in supramolecular organization
Biochemistry (Moscow), 2014Archaeal flagella are similar functionally to bacterial flagella, but structurally they are completely different. Helical archaeal flagellar filaments are formed of protein subunits called flagellins (archaellins). Notwithstanding progress in studies of archaeal flagella achieved in recent years, many problems in this area are still unsolved.

Evolutionary advantages of polyploidy in halophilic archaea
Biochemical Society Transactions, 2013Several species of haloarchaea have been shown to be polyploid and thus this trait might be typical for and widespread in haloarchaea. In the present paper, nine different possible evolutionary advantages of polyploidy for haloarchaea are discussed, including low mutation rate, radiation/desiccation resistance, gene redundancy and survival over ...
